- Key result
- Temp.:
- ca. 20 °C
- Vapour pressure:
- ca. 0.001 Pa
- Conclusions:
- Under the study conditions, the vapour pressure of the test substance was determined to be 0.00108 Pa at 20°C.
- Executive summary:
A study was conducted to determine the vapour pressure of the test substance using the isothermal thermogravimetrical effusion method according to the OECD Guideline 104 and EU Method A.4, in compliance with GLP. Under the study conditions, the vapour pressure of the test substance was determined to be 0.00108 Pa at 20°C (Wohr, 2019).
Reference
The evaluation of the vapour pressure was done with the reproducible weight loss values above > 1 μg/min in the temperature range between 130 °C and 160 °C. The vapour pressure of the test substance was estimated to be 1.08 x 10-3 Pa at 20°C.
Description of key information
The vapour pressure of the test substance was determined using the isothermal thermogravimetrical effusion method according to OECD Guideline 104 and EU Method A.4 (Wohr, 2019).
Key value for chemical safety assessment
- Vapour pressure:
- 0.001 Pa
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
